NMR Spectroscopy as a Cornerstone Technique in the Undergraduate Chemical Curriculum

核磁共振（NMR）是一种强大的结构测定和定量技术，广泛应用于所有科学领域。在传统的本科课程中，除了大二的有机课程外，NMR的实践经验通常是有限的。这个项目使用核磁共振作为九个本科实验课的基础技术。除了在有机化学和无机化学中识别和表征结构的传统用途外，NMR还被用于分析化学、物理化学和生物化学实验室中演示原理。该项目的具体目标是通过使用核磁共振作为基础技术，提高学生对化学原理的理解，使学生在他们的职业生涯中熟练掌握。为了实现我们将核磁共振扩展到二年级有机实验室之外的目标，我们正在使用现代化的高场核磁共振光谱仪。新仪器可用于化学专业的学生和非专业的学生，包括大二到大四的化学实验课。发表的实验，主要来自化学教育杂志，正在调整和整合在九个课程中，以实现我们的课程目标。教程页面用于引导学生完成标准NMR数据文件的传输和处理，处理系统以佛罗里达州立大学使用的系统为模型。最后，每年为有兴趣在我们的NMR上运行学生样本的区域四年制机构提供一个研讨会。结果通过电子邮件发送给学生，然后学生使用具有所有标准核磁共振处理功能的软件来分析他们的数据。智力优势：在课堂上使用技术对于教授现代科学概念和吸引熟悉计算机的学生越来越重要。核磁共振是一项核心技术，因为它可以用来研究各种问题。这个项目导致了一些新的实验室实验的发展，这些实验将提供给其他有兴趣在他们的实验室课程中增加使用核磁共振的教师。更广泛的影响：拟议的项目每年涉及约300名本科生。这些学生获得实践经验，作为学习基本化学概念的一种手段。我们也希望通过这个项目，学生们会对化学和科学产生兴趣。特别是，通过接触非专业的学生，我们希望鼓励这些学生，特别是那些来自代表性不足的群体的学生，考虑从事科学领域的职业。

Chemistry (12) Nuclear Magnetic Resonance (NMR) is a powerful technique for structural determination and quantification that is widely used across all areas of science. In the traditional undergraduate curriculum, hands-on experience with NMR is typically limited outside of sophomore organic classes. This project uses NMR as a cornerstone technique in nine undergraduate laboratory classes. In additional to traditional uses of NMR to identify and characterize structures in organic and inorganic chemistry, NMR is being used to demonstrate principles in analytical, physical chemistry, and biochemistry labs. The specific goal of this project is to improve student understanding of chemical principles, by using NMR as a cornerstone technique, with which students become proficient over their career. To achieve our goals of expanding NMR beyond the sophomore organic lab, we are using a modern, high-field NMR spectrometer. The new instrument is used in a hands-on fashion by both chemistry majors and non-majors taking sophomore through senior level chemistry lab classes. Published experiments, primarily from the Journal of Chemical Education, are being adapted and integrated within the nine courses in order to achieve our curricular goals. A tutorial page is used to walk students through the transfer and processing of a standard NMR data file, with the processing system modeled on one used at Florida State University. Finally, a workshop is being offered annually to regional four-year institutions that are interested in having student samples run on our NMR. The results are e-mailed back to the students who then use software capable of all standard NMR processing functions to analyze their data.Intellectual Merit: The use of technology in the classroom is of increasing importance to teach modern scientific concepts and engage computer literate students. NMR is a central technique since it can be used to study a variety of problems. This project is leading to the development of a number of new laboratory experiments, and these experiments will be made available to other instructors interested in increasing the use of NMR in their laboratory classes. Broader Impact: The proposed project is involving approximately 300 undergraduate students per year. These students receive hands-on experience as a means to learn fundamental chemical concepts. We also expect that students will be excited about chemistry, and science in general, as a result of this project. In particular, by reaching out to non-majors we hope to encourage these students, particularly those from under-represented groups, to consider careers in the sciences.
